“My Uncle Milton and my dear friend Charlene’s mom lost their fight to ALS. In their honor and all of the families that are affected by ALS, I’m donating money and also accepting the ice bucket challenge,” the 34-year-old supermodel wrote with her video. “I am challenging Anna Wintour, Mario Testino, and Shakira.”

Fellow models who recently completed the challenge include Anne V, Suki Waterhouse, and Brooklyn Decker. They are all raising awareness for the disease, which affects the nerve cells in the brain and spinal cord that control voluntary muscle movement.
